Abstract
A cylindrical alkali halide melt-grown single-crystal-type ingot is axially compressed in a heated dual-platen press while in a plastic state. The ingot is located mid-way between two parallel, planar, vertically extending barriers. By properly orienting the platens and the barriers with respect to the crystal lattice structure of the ingot, the ingot can be forged into a rectangular block that is not only devoid of peripheral cracks and fissures but that also has more uniform properties even when impurities and activator (Tl, in the case of NaI(Tl)) are not uniformly distributed within the initial single-crystal ingot.
